I have two bikes (both with square taper BB's that use M8 bolts), and I have one set of Ti crank bolts, and one set of alloy that I'm considering using.
I've been searching for some good info on how to use these bolts responsibly, but I haven't found any concrete advice.
I know that a steel bolt should be used first and torqued to spec, but how about the lighter bolts? My search has yielded torque recommendations (for alloy) ranging from ~20-88 in/lbs. One report of alum bolts shearing at 25 in/lbs.
Does anyone have some really good advice on how to use both of these types of crank bolts responsibly?
